LOOM CLOTH ROLL TAKE UP This is a continuation in part of our copending application Ser. No. 353,237 filed Apr. 23, 1973 for LOOM CLOTH ROLL TAKE UP.

This invention relates to an improved cloth roll take up for a loom wherein a pair of transversely spaced members are carried outboard of the loom frame members adjacent the rear of the loom for carrying driven roll supports above the loom for receiving cloth from beneath the loom behind the loom beam. Such an arrangement permits the building of a very large cloth roll without interference with the various loom parts while saving space in the mill to accommodate personnel and auxiliary equipment. This invention further relates to a take up having means guiding the cloth from the delivery roll and directing same laterally beneath a side frame member to a take up roll.

BACKGROUND OF THE INVENTION Loom cloth roll take ups have been proposed wherein surface driven take up rolls are carried on the top of the loom and mounted on the loom frame. Such structure is shown in British Pat. No. 1,018,109 published Jan. 28, 1966 and similar structure is shown in United States Letters Pat. Nos. 2,811,176, 3,502,115 and 3,677,305. The prior art also contemplates a Winding mechanism comprising a pair of spaced horizontal transverse frictional take up rolls which are suitably driven and mounted forwardly of the loom, such as illustrated in US. Letters Pat. No. 3,433,430, but space requirements are increased thereby. It has heretofore proved to be impractical, however, in practice to position frictional take up rolls over the loom for building very large rolls while conserving space within the mill. It has been found that exceptional vibration is imparted from the loom frames to the take up mechanism carried thereby. Moreover, in the case of very large rolls, it is necessary that the take up mechanism be cantilevered outwardly behind the loom to avoid interference of the cloth with the loom beam.

It is important to overcome the vibration problem and provide a practical structural arrangement for sup porting the take up equipment plus the very large cloth roll while avoiding obstructing the working mechanism of the loom. It is also important to provide effective mechanisms for exerting control over the cloth for building a tight very large cloth roll while disposed out of the way of the loom parts, as well as personnel and auxiliary roll doffing equipment such as lift trucks, etc.

A further important object of the invention is to avoid obstruction of the loom beam and associated parts in the back of the loom by providing a take up which directs the cloth laterally beneath the loom.

SUMMARY OF THE INVENTION It has been found that by positioning spaced vertical frame members, each including a pair of longitudinal standards, outboard of the frame members of the loom, it is possible to avoid excessive vibration and provide sufficient support to carry the required load in a position to avoid interference by the cloth with the loom beam.

Since the frame members are constructed of spaced standards, reasonable access may be had for operating and maintaining the various conventional loom parts with which the device is used. It has further been found that a take up mechanism having a pair of driven spaced horizontal transverse frictional take up rolls with means for guiding the cloth thereto, including a transverse roll carried in horizontal alignment with an adjacent take up roll, afi'ords effective control upon the cloth by maintaining a predetermined wrap of the cloth about the adjacent take up roll.

An imperforate dirt shield is carried by the loom in superposed relation to a width of cloth passing beneath the loom. The driving means preferably includes a reversible motor driving one of the take up rolls at a first speed, a driving connection between the rolls causing the one roll to impart rotation at a slightly different second speed to the other roll for building a tight cloth roll, and means releasing such driving connection when the motor is reversed to permit an even take off of cloth avoiding any tendency to pucker.

By positioning the vertical frame members outboard of the loom frame members, a sufficiently rugged structure can be afforded to carry the various drive mechanisms for the frictional rolls above the loom while isolating the drive and take up mechanism from the oscillations and vibrations during weaving. Horizontal alignment of the peripheries of the transverse roll and a take up roll facilitates a manual placement of a full cloth roll thereon making it more accessable to the tines of a lift truck for doffing.

It has further been found that guide means may be positioned beneath the loom, rearwardly of means for guiding cloth from the delivery roll for directing the cloth laterally beneath a loom side frame member in open width to means positioned laterally of the loom for directing the cloth to the take up roll.

DESCRIPTION OF A PREFERRED EMBODIMENT The drawing illustrates a cloth roll take up for a loom having a loom beam adjacent the rear of the loom and a cloth delivery roll mounted to receive woven cloth A pair of transversely spaced vertical frame members A, each including a pair of longitudinally spaced standards, are carried outboard of the loom frame members adjacent the top of the frame members. A pair of spaced horizontal transverse friction take up rolls C are carried for rotation by a pair of spaced roll supports D. The roll supports are carried by the platform in transverse alignment therewith for supporting the pair of take up rolls for rotation above and in substantial vertical alignment with the loom beam. Means E for driving the pair of take up rolls are carried by the platform. Means F are provided for guiding the cloth from beneath the loom substantially vertically behind the loom beam to the take up rolls. Preferably, the means for guiding the cloth from beneath the loom includes a transverse roll carried in horizontal alignment with an adjacent take up roll C for affording a predetermined wrap of the cloth thereabout.

A loom of standard construction is broadly designated at and includes a pair of side frame members 11 and 12 bridged by the usual breast beam 13. A loom beam 14 is carried adjacent the rear of the frame members 11 and 12 and supplies warp yarn 15 over the usual whip roll 16. The warp yarn 15 forms a shed 16a for making the cloth 17 which is illustrated as passing over the breast beam 13 to the usual delivery or take up sand roll 18. At this point the procedure varies from the conventional and the cloth is carried over a press roll 19 and thence downwardly around a pair of guide rolls 20 and 21 beneath the loom preparatory to its being guided by the mechanism hereof and wound into a very large cloth roll.

A pair of transversely spaced vertical frame members A each including a pair of longitudinally spaced standards 22 are braced at the bottom by cross frame members 23 and at the top by the various components of the mounting platform B which bridge the respective standards 22 and extends transversely between the respective vertical frame members A.

The platform B on the left hand side of FIG. 1 includes spaced horizontal transverse members 24 which are bridged by a suitable longitudinal frame member 25. The frame A on the right hand side of FIG. 1 is bridged by a longitudinal member 26. The platform further includes a transverse frame member 27 which bridges the longitudinal frame members 25 and 26 to provide rigidity to the platform structure as well as the frame members which support it. Suitable angularly disposed frame members 28 may be employed as desired to add rigidity to the aforesaid frame and platform structure. An additional transverse member 29 (FIG. 2) spans the vertical frame members and carries a pair of spaced standards 30 for limiting transverse movement of the cloth roll upon the frictional take up rolls C. The transverse frame member 29 is secured to the frame and platform members through a pair of spaced roll supports D.

The means E for driving the pair of take up rolls C are carried by the platform and contained within a suitable housing 31. The means E includes a motor 32 which through a gear box 33 drives a chain 34 for imparting rotation to the frictional take up rolls C through a sprocket 35. The sprocket 35 is carried by the forward roll 36 of the rolls C. The back roll 37 is driven through a sprocket 38 which, in turn, is driven through an endless chain 39 driven by the sprocket 40 carried by the opposite end of the roll 36.

A means F for guiding the cloth beneath the loom includes a guide roll 41 carried by extensions 42 of the frame members 11 and 12 and is positioned to guide the cloth upwardly substantially vertically behind the loom beam to a cooperating transverse roll 43 which controls the wrap of the cloth 17 and the adjacent frictional roll 37. Thus, the tension exerted upon the cloth 17 as it is wound about a suitable core 44 to form a cloth roll 17a, is continuously built upon the frictional rolls C to a very large size.

An imperforate dirt shield 17b is carried by brackets by the loom side frame members just above the run of cloth passing beneath the loom. The motor 32 is preferably a reversible motor for backing cloth off the cloth roll producing slack in the vertical run of cloth past the loom beam. Thus, access may be had as when a warp end comes down. It has been found desirable, in order to get a tight warp on cloth on the cloth roll, to drive one of the take up rolls at a slightly faster speed than the other. In the embodiment illustrated the take up roll 36 is driven faster, having one less tooth than take up roll 37. As noted in FIG. 3A, a ratchet wheel 45 is keyed to the shaft carrying roll 37 as at 45a. A spring biased pawl 46 is pivoted as at 46a upon the sprocket. During reversing the pawl will be out of engagement with the ratchet so that the rolls 37 and 36 will be driven at the same speed as has been found necessary to avoid placing a pucker in the cloth roll on reversing.

A modified form of the invention is illustrated in FIG. 3 wherein like parts are designated by like reference characters with prime notations added. A pair of longitudinally spaced vertical frame members A are carried independently of the loom frame members. A pair of spaced horizontal friction take up rolls C are carried for rotation on a pair of spaced roll supports D. The roll supports are preferably carried by a platform B in alignment therewith for supporting the pair of take up rolls for rotation above said loom. Means E for driving the pair of take up rolls are carried by the platform.

Means F are positioned laterally of the loom receiving the cloth and directing same to the cloth roll take up. A guide bar or roll G is positioned beneath and across the loom, rearwardly of the means for guiding the cloth from the delivery roll, receiving the cloth and directing same transversely beneath a loom side frame member.

A loom is broadly designated at 10' and includes a pair of side frame member 11 and 12. A loom beam 14 is carried adjacent the rear of the frame members 11 and 12' and supplies warp yarn 15' over the usual whip roll 16. Cloth 17' is illustrated as passing over the usual delivery or take up sand roll 18'. At this point the cloth is beneath the loom on the roll 21 preparatory to its being guided by the mechanism hereof and wound into a very large cloth roll.

A pair of transversely spaced vertical frame members A are braced as by cross frame member 23 and at the top by the various components of the mounting platform B which preferably bridge the respective frame members.

The platform B on the right hand side of FIG. 3 includes longitudinal frame member 27 which bridges the frame members A to provide rigidity to the platform structure as well as the frame members which ssupport it. A pair of spaced standards 50' for limiting transverse movement of the cloth roll upon the frietional take up rolls C are carried upon the platform.

The means F. for driving the pair of take up rolls C are carried by the platform and contained within a suitable housing 31'. The means includes a motor (not 5 shown) which through a gear box 33 drives suitable drive means for imparting rotation to the frictional take up rolls C as shown in FIG. 1.

Means F are positioned laterally of the loom to guide the cloth upwardly substantially vertically longitudinally of the loom to the cloth roll take up which includes the rolls C".

The guide bar on roll G is illustrated positioned beneath and across the loom at substantially a angle. The bar G is illustrated as being stationary with an integral flat extension which is secured as by a bolt 5] to a bracket 52 suitably secured to respective loom sides as by bolts 53. The rearward cloth contacting the edge of the bar is preferably rounded as at 54. It will be observed that the upward course of the cloth passes outside the picker sticks 55 and does not substantially limit access to loom parts.

Another modified form of the invention is illustrated in FIG 4. Warp yarn passes from the loom beam and is woven into the cloth 61 which passes in a vertical downward flight over the loom take up roll 62. The cloth then passes under a roll 63 beneath the loom to a guide bar 64.

The guide bar 64 is positioned beneath and across the loom, rearwardly ofthe means in the form of roll 64 for -guiding the cloth from said delivery roll. The bar, or roll 64 receives the cloth from the roll 64 and directs same laterally beneath and beyond the loom. A roll 65 is positioned laterally of the loom receiving the cloth from the roll 64 directing same upwardly. Thus, the cloth roll take up may be positioned in a desired position remote from the loom. It is even contemplated that the cloth roll take up could be positioned on the floor and passed directly thereto instead of to the roll 65.

Means similar to those shown in HQ. 3 are provided for mounting the cloth roll take up broadly designated at 66 above and across a forward portion of the loom. A second guide bar 67 is positioned above and across the loom receiving the cloth from the roll 65 via roll 68 directing same longitudinally forwardly to said cloth roll take up.
